JLS have teamed up with One Direction for a special charity competition.

As previously reported, the 'Hottest Girl In The World' stars recently revealed that they were partnering with Cancer Research for a new fundraising drive in association with the JLS Foundation.

One of their initiatives is to run a competition which sees the winner attend a soundcheck with a "mystery boyband" and spend time with JLS, before watching the "secret" act at London's O2 Arena.

It has now been confirmed that One Direction are the "mystery" group.

The competition costs £1 to enter and people can enter as many times as they would like.

The prize draw ends at midday on Friday (December 21), with the events taking place in spring next year.
